Abstract
Description
Technical Field
[0001] This application relates to the field of blueprint production technology, and more particularly to a coating apparatus for blueprint production. Background Technology
[0002] Blueprint paper is a type of chemically coated paper specifically designed for blueprinting in various engineering designs and mechanical manufacturing processes. It is an indispensable item in production, scientific research, and construction. Commonly known as "blueprint paper" or "blueprinting paper," it features the characteristics of being reproducible, easy to preserve, non-blurring, non-fading, resistant to staining, and unalterable. The production process of blueprint paper requires a coating machine to coat its surface.
[0003] A published patent document (CN211000426U) discloses a blueprint coating machine. This device uses a fan to extract harmful gases from the main body of the machine, which are then filtered through an activated carbon filter to absorb the irritating odors, making the working environment safer and improving the practicality of the blueprint coating machine. However, in operation, the device uses a nozzle above the ink roller to spray ink onto the ink roller, which then applies ink to the blueprint paper. During the ink spraying process, the nozzle is prone to clogging, resulting in uneven ink application on the ink roller and an uneven surface finish on the blueprint paper. Utility Model Content

[0013] As a preferred technical solution of this application, gaps are left between the outer wall of the stirring roller and the ink coating roller and the inner wall of the ink immersion box.
[0014] By adopting the above technical solutions, the safety of the device during use is ensured.
[0015] As a preferred technical solution of this application, the upper surface of the ink immersion box is symmetrically connected with scrapers on both sides of the ink coating roller, and the scrapers are arranged in an arc shape on the side closer to the ink coating roller.
[0016] By adopting the above technical solution, excess ink on the coating roller is scraped off by a scraper, ensuring that the ink is evenly distributed on the outer wall of the coating roller, which helps to improve the coating quality.
[0017] As a preferred technical solution of this application, the clamping unit includes a positioning frame fixedly installed on the surface of the workbench. Two electric telescopic rods are symmetrically installed on the top of the positioning frame. The output ends of the two electric telescopic rods slide through the positioning frame and are fixedly connected to a connecting block. A clamping roller is rotatably installed between the two connecting blocks.
[0018] By adopting the above technical solution, the height of the pressing roller can be adjusted by the cooperation between the electric telescopic rod and the connecting block, enabling the device to press blueprints of different thicknesses.
